The interactive signal generating apparatus of loose impediment of the present invention can apply in the following operational instances:
I. the simulated flight sound and the light of the model of an airplane
Interactive signal generating apparatus 10 of the present invention is installed in the model of an airplane 20, and the hand-holdable model of an airplane 20 of user aloft moves.Speed sensitive unit 12 measure 3-axis acceleration (Ax, Ay, Az), through microcontroller 14 programs be converted into three speed (Vx, Vy, Vz), with each speed V
i, i=x, y, z is as the source of sound frequency parameter of simulated aircraft flight.This microcontroller 14 can the overall treatment three-dimensional speed, and this database 16 acquisition corresponding preset audios 163 certainly, and drive this loudspeaker 24 via interactive signal output control unit 18 form with the message data audio mixing that all are corresponding.Moreover this microcontroller 14 can compare speed the maximum of three-dimensional, with from database 16 acquisition corresponding preset audio data 163, and drives this loudspeaker 24 via interactive signal output control unit 18.
The audio of for example lifting following corresponding different directions axle is an example:
Vx is the aircraft working direction, and default audio data 163 can comprise the source of sound of emulation aircraft flight;
Vy is the aircraft left and right directions, and what default audio data 163 can comprise the left-handed dextrorotation of emulation aircraft flight exhales heavy breathing sound;
Vz be aircraft quicken up or stall down, default audio data 163 can comprise emulation aeroengine sound.
(Vz) the maximum is then from database 16 acquisition corresponding preset audio data 163 for Vx, Vy so microcontroller 14 compares three speed.For example if Vy greater than Vx and Vz, then microcontroller 14 is delivered to loudspeaker 24 then from the message data of exhaling heavy breathing sound of the left-handed dextrorotation of database 16 acquisition corresponding simulating aircraft flights.Moreover, this microcontroller 14 can for three-dimensional speed (Vx, Vy, Vz) overall treatment, that is when three-dimensional speed (when Vz) one of them surpassed critical value (referring to the threshold speed data 161 in the database 16), promptly in addition audio mixing was handled for Vx, Vy.When all exceeding critical value as Vx and Vy, this microcontroller 14 is from the message data of the corresponding aircraft flight of database 16 acquisitions, and the message data of exhaling heavy breathing sound of the left-handed dextrorotation of emulation aircraft flight, with two message data audio mixings, at last the audio mixing data are delivered to loudspeaker 24 again.
Have the different audios at the particular flight dimension except above-mentioned, also can set for the sound frequency or the variation of glow frequency for the velocity amplitude of different dimensions.Referring to Fig. 5, be example with sound, can be for the speed-sound frequency transformational relation of each dimension direction setting correspondence, or acceleration-sound frequency transformational relation.
Cooperate Fig. 5, this speed-sound frequency transformational relation for example can be as following formulate:
Sound=
As can be seen from the above equation, for the speed Vx of each dimension direction, Vy, Vz have specific transfer function (conversion function) f
1, f
2, f
3(as linear function, polygronal function or Gaussian function etc.) computing in addition.And in different frequencies different weighted value (weight) is arranged, that is f (n), n=1,2,3.Whereby can be according to the speed that measures, and the different sound of conversion.Aforesaid transfer function and weighted value are present in the transfer function and weighted value data 160 of this database 16, and for the different dimensions direction different transfer functions and weighted value can be arranged.
Be under the situation of straight line at transfer function for example, and adopt fixing weighted value, then the speed of the model of an airplane 20 is fast more, and the sound frequency of loudspeaker 24 is high more.Moreover (Vx, Vy Vz) can adopt the linear function of Different Slope to corresponding three-dimensional direction speed, and (three audio signals audio mixings that Vz) produced are to drive loudspeaker 24 for Vx, Vy to three-dimensional speed again.Therefore when the hand-held model of an airplane 20 simulated flight in 3d space of user, foundation interactive signal generating apparatus 10 of the present invention can send the sound effect of aircraft flight according to space tracking, and the flight sound of each hand-held flight all can be different in theory.Moreover above-mentioned frequency inverted relation can be applied on those lamps, if aircraft flight speed is fast more, then the lamp flicker frequency is high more.
II. the flight path audio of the model of an airplane
Referring to Fig. 6, this database 16 comprises default track pattern data 166, as shown in the drawing, the default flight path pattern of database 16 records, for example circular (circle), triangle (triangular), 8 fonts (8-shaped) or square (square), and the special sound effect data 164 of corresponding those patterns.If interactive signal generating apparatus 10 is sensed the default flight path pattern of track correspondence database 16 records of aircraft, for example circular (circle), triangle (triangular), 8 fonts (8-shaped) or square (square), then microcontroller 14 can drive loudspeaker 24 and can send corresponding special sound effect (bonus soundtrack), to reward and to inform the user.Moreover, when microcontroller 14 perceives the track that this model of an airplane 20 has hand-held vibrations, then can drive this loudspeaker 24, to send machine gun sound.
III. the simulated flight light of the model of an airplane
Cooperate shown in Figure 2ly, suppose that Vx is that aircraft working direction, Vy are aircraft left and right directions and Vz is the aircraft above-below direction.When microcontroller 14 is learnt the three-dimensional speed/acceleration value of the model of an airplane 20, and with the threshold speed data 161 of database 16 and acceleration threshold data 162 in critical value relatively.When the Vy value surpasses certain critical value, may be defined as about aircraft and turn to, so microcontroller 14 can see through interactive signal output control unit 18 drive left and right sides wing lamp 22A, 22B one of them, with the expression aircraft left or turn right.When the Vx value surpass necessarily on the occasion of the time, the definable aircraft is in in-flight, so microcontroller 14 can see through the lamp 22C that interactive signal output control unit 18 drives tails, send the state that sprays light with the simulation tail.
Moreover on the above-mentioned model of an airplane 20, can set up operating selection switch (not shown), to choose one of above-mentioned three kinds of operator schemes, or other operator scheme, for example this microcontroller 14 can be subjected to the control of operating selection switch, and choose the flash mode data 165 of database 16, and drive those lamps with AD HOC (for example flicker or flicker in proper order at random).
In sum, when knowing that interactive signal generating apparatus and method that the present invention is used for loose impediment have had industry applications, novelty and creativeness, again because structure of the present invention had not seen like product and public use yet, meet the application for a patent for invention important document fully, file an application according to Patent Law.
